Direction Finding Technique by Time-Modulated Arrays for Multiple Correlated Signals

Abstract

This paper presents a novel Direction Finding technique by Time Modulated Arrays for multiple correlated signals. The method is based on the comparison between the obtained harmonics data from the output of the array, with a Look Up Table made of pre-computed values. A simulation of a concentricrings array consisting of three rings is conducted to validate the proposed method. The resulting spatial spectrum demonstrates that the proposed method can successfully estimate the DoA of two correlated sources.
